CAR-DOOR.

SPECIFICATION forming part of Letters Patent No. 636,040, dated October 31, 1899. Application filed July 10, 1899. Serial No. 723,342. (No model.)

To all whom it may concern:

Be it known that I, LOUIS A. I-IOERR, a citi Zen of the United States of America, residing at St. Louis, in the State of Missouri, have invented a certain new and useful Oar-Door, of whichthe following is such a full,clear,and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification. V

One object of my invention is to provide a flush door for cars which will be simple of construction and reliable in operation.

Another object of my invention is to provide a more perfectly waterproof door than has heretofore been constructed.

Still another object of my invention is to so construct the door that the strain will be taken off the hangers when the door is closed, thus greatly lessening the liability of the hangers being broken.

My invention consists in part in the combination, with a car, of a door set into the car so as to be flush with the side thereof, a track, a hanger rigidly secured to said door and slid ing on said track, and means for moving said hanger laterally to cause said door to clear the side of the car when it is opened.

My invention also consists in various other novel features and details of construction, all of which are described in thefollowing specification and pointed out in the claims affixed hereto.

In the accompanying drawings, which illustrate one form of car-door made in accordance with my invention, Figure 1 is a side elevation of the door and so much of the side of the car as is necessary to illustrate my invention. Fig. 2 is a section on the line 2 2 of Fig. 1. Fig. 3 is a section on the line 3 3 of Fig. 1. Fig. 4 is a section on the line 4 4 of Fig. 1. Fig. 5 is an enlarged sectional view Fig.1

' lar 31.

Fig. 11 is an enlarged section on the line 11 11 of Fig. 1.

Like marks of reference refer to similar parts in the several views of the drawings.

15 is the side of the car, and 16 a flush door set into the side 15 of the car, as usual.

17 is the door-track, which is bolted to the side 15, but held out of contact therewith by a track-fillet 18. The top of the track 17 is preferably made flush with the top of the fillet 18, so as to form a water-shed. The track 17 gradually approaches the side 15 from a point about the middle of the door 16 to the front edge of the said door in the usual manner, as is shown in Figs. 2 and 3.

- 20 is a hanger which is secured to the door 16 near its front edge and is preferably provided with a roller 21, bearing on the top of the track 17. The hanger 20 is also provided with an upwardly-projecting lug 22, Figs. 3 and 7, preferably made integral with the said hanger, and which bears against the inner side of the track 17 Rigidly secured to the door 16, near the rear edge thereof, is a hanger 24, which is adapted to slide laterally on the track 17 and .fillet 1S. Journaled in the hanger 24 is a rock-shaft 25. $ecured to the top of the rock-shaft 25 or formed integral therewith is a cam or eccentric 26, which is adapted to bear either against the side 15 of the car or the inner face of the track 17 to throw the door in or out laterally, as will be hereinafter described. The cam 26 may bear directly against the side of the car 15; but I much prefer to interpose between the said parts a metallic strip 27, Figs. 5 and 6, to prevent wear on the side of the car. The lower face of the upper memberof the hanger 24 is preferably inclined slightly upward at its inner end, as best shown in Fig. 5, so as to prevent its wearing the upper face of the wooden fillet 18.

The lower end of the rock-shaft 25 passes through a lug 29 and has rigidly secured to it a collar 30. Loosely mounted onthe shaft 25, between the lug 29 and collar 30, is a col- The collar 30 is provided with a shoulder 32 and the collar 31 with a shoulder 33, which are adapted to come in contact when the collar 31 is rotated. Some play, however, is allowed between the shoulders 32 and 33, so that the collar 31 may be rotated a short distance without aifeetin g the collar 30 and shaft 25. The abutting ends of the eollars 31 and 32 are slightly inclined, as shown in Fig. 8, so that when the hasp, hereinafter to be described, is in its open position the jolting of the car will tend to keep it against the side of the car, as otherwise it might swing out at right angles to the car and be injured by striking against any object near the track on which the car was moving. Extending from the car 3l,and preferably form ed integral therewith, is a hasp 31, which is adapted to engage with a detent 35. The detent 35 is pivotally and slidingly mounted in a pocket 36, set into the side of the car 15. The downwardly-extending ways 36, Figs. 5) and 10, in the pocket 36, in which the detent 35 slides, are inclined slightly forward, so that not only the jolting of the car, but also any outward pull on the hasp 34., will tend to seat the detent more firmly in the said hasp. The hasp 31 is preferably provided with a lug 37, and an opening 38 is formed through the detent and lug 37, through which an ordinary seal-wire may be passed.

At the lower front corner of the door a guide-bracket 40 is secured to the side of the car 15. The rear edge ll of the bracket 40 is preferably inclined outward, as best shown in Fig. 1. A guide-bracket 42 is secured to the side 15 at the lower rear corner of the door. The guide 12 is provided with a rubknob 13, Fig. 4, preferably formed integral therewith, against which the inner face of the door 16 bears when the door is being opened. The door is preferably provided with a rubstrip 44 of the usual form, which bears against the guide-bracket 42 when the door 16 is opened or closed. A Z-shaped metal plate 45, Figs. 1 and 11, is also preferably secured in the bottom of the door-opening.

4.6 is a handle, which may be of any usual form.

47 are two rub-knobs which are secured to the side 15 at about the middle of the height of the door 16 and are adapted to prevent the door 16 from rubbing against the side of the car 15 when said door is being opened or closed.

18 is a stop which is adapted to limit the rearward movement of the door 16 and also to prevent its rear edge from swinging outwardly when the door is open.

In order to open the door, the detent 35 is first raised and the hasp 3i drawn outwardly. The detent 35 is then released, when it will fall down by gravity into the pocket 36, as shown in Fig. 10, so as to be entirely out of the path of the door. \Vhen the shoulder 33 comes in contact with the shoulder 32 of the collar 30, the rock-shaft 25 will be rotated. This will swing the cam 26 against the metal strip 27 and move the door 16 and hanger 21 outwardly into the position shown in Fig. 6. The rear edge of the door 16 will now be clear of the side of the car 15, and the door can be moved back 011 the track 17. As the door moves back, the front edge of the door will be thrown outward owing to the outward travel of the front hanger 20, which follows the track 17. When it is desired to close the door, it is slid forward along the track 17, the front edge being guided into the recess in the side of the car owing to the form of the traek17, which is followed by the hanger 20. \Vhen the door is in its forward position, the detent 35is raised and the hasp 34 swung into position to be engaged by the said detent. This will cause the rock-shaft 25 to be rotated and throw the cam 26 against the track 17, as shown in Fig. 5, thus forcing the rear edge of the door firmly into its seat in the side of the ear. The lower edge of the door will be held in position by means of the guide-bracket 10 and the hasp 34.

As the door is held firmly in its seat, flush with the side of the car, a tight joint is formed between the door and the side of the car, thus preventing the entrance of rain. As the tops of the fillet 18 and track 17 are flush, said parts form a watershed at the top of the car, preventing any water running down from the roof of the car fromentering the top of the door and obviating the necessity of a hoodboard, such as is usually used. As the door is held in position by the cam 26 bearing on the track 17, the strain is entirely taken off the hanger when the door is in its closed position, thus greatly reducing the liabilityof the hanger being broken and the consequent disabling of the door.

It will be seen that while my dooris simple A of construction it is effective and reliable in action, and on account of its simplicity of construction it is not liable to get out of order.

Many changes may be made in the form and construction of my door without departing from the spirit of my invention, and I do not wish to be limited to the exact form and construetion shown except where specifically so stated in the claims.
